EFI Fuel Tank Kit with 255 LPH Pump for 1974-1977 Chevy Vega
Swapping an LS or LT engine into a classic Vega requires a fuel system that matches its output and this EFI tank kit pairs a 255 LPH Walbro pump with a corrosion-resistant steel reservoir built for 1974 to 1977 underbody mounts. By relocating the pump module inside the tank, this assembly holds steady pressure, shortens fuel line runs, and cuts vapor lock risk during spirited driving. Featuring a 19 gallon capacity and silver coated galvanized finish, the reservoir extends driving range while preserving Vega undercarriage lines and fending off corrosion. Completing the kit are the OEM style sending unit, vent filter, gaskets, and full mounting hardware so installers have every piece needed for a clean EFI conversion on a 1974 to 1977 Vega.
Precision Fuel Delivery for High Output Engines
The 255 LPH Walbro pump is engineered to support engines up to 550 horsepower while maintaining consistent pressure under rapid throttle changes. By positioning the pump inside the fuel tank, the assembly keeps fuel cooler and minimizes air entrapment that can cause vapor lock during spirited runs. Shorter fuel line routing from the tank to the engine ensures immediate response to driver input and uniform flow at all engine speeds. As a result, this configuration preserves calibration accuracy for reliable fuel metering even under the most demanding conditions.
Corrosion Protection with Galvanized Steel and Silver Finish
The tank body is formed from steel that has undergone a galvanizing process, creating a zinc barrier against rust and corrosion. A silver powder coat is then applied to seal the surface, delivering resistance to road salts and moisture that can mar undercarriage components. This dual treatment bonds tightly to the steel, reducing the chance of chips or scratches exposing bare metal. Together, these layers ensure the reservoir maintains its appearance and structural integrity for years beneath a classic Vega.
Integrated Module Design Simplifies EFI Conversion
This kit combines the pump, sending unit, vent filter and filler neck into a single assembly that aligns with factory underbody mounting points on 1974–1977 Vegas. All necessary straps, gaskets and hardware are included to eliminate the need for aftermarket modifications or custom brackets. The original equipment style sending unit preserves accurate fuel level readings without altering the dash cluster. By grouping components into one cohesive module, installers can complete the swap more efficiently and avoid compatibility issues that arise from mixing parts.
Large Capacity Tank Enhancing Range and Consistent Flow
With nineteen gallons of capacity, the tank extends driving range for long cruises or track sessions and reduces the frequency of refueling stops. Internal baffling controls fuel movement, preventing starved pump pickup during hard cornering or rapid acceleration. This stability maintains uninterrupted flow, which translates to smoother acceleration and precise throttle response. Whether tackling a winding back road or embarking on a cross-country journey, drivers benefit from both endurance and performance assurance.
